Did anyone else get this terrifying encounter?

[Turikan]

I had opened that door from the opposite side, (I was pulling the door open towards me) so I never saw him, but when the door was halfway open he roared.
I slammed the door shut, and was holding it closed when he started banging on it. I ran away and hid for a few minutes, then deciding it was safe ventured out to take a look.
I saw the door was still closed and approached it again, thinking it might have been a scripted event. As soon as I got close he roared and banged again, at which point I ran and hid... again XD
Then I decided just to avoid that door and went on my marry way completing my objective for that area. Upon returning to that room I noticed that door was opened. I had to quit playing the game for a little while after that
